[GIS] Counting number of points in exact same location using ArcGIS Desktop

arcgis-10.2arcgis-desktopoverlapping-features

I have a points shapefile where in any given location there may be one point, two points, or three points on the exact same spot.

Any suggestions on how to count those up so I get one point at each location, but a count of how many points were there before?

This can be done using the Dissolve tool on the layer, leaving all the Dissolve Fields unchecked, and adding ObjectID as a Statistics Field with COUNT as the Statistic Type. As has been pointed out though, ArcGIS' definition of the "exact same spot" may differ from yours depending on what you're doing.
